To all whom it may concern.'

Be it known that I, GABRYELMROCZKOWSKI, a subject of the Czar of Russia, residing at hicago, in the county of Cook and. State of Illinois, have invented certain new and useful Improvements in Folding Umbrellas,`-

of which the f: `lowing is My present umbrellas, and ter of folding umbrella embodying ribs in foldable inner and outer sections having means :to lock said rib parts'in longitudinal alinement when the umbrella is unfolded, whereby the umbrella may be opened and closed (raised and lowered) in use, similaito the ordinary non-foldable umbrella.

The principal object of my invention is to provide .simple and inexpensive means to accomplish the foregoing, which will be adapted to a particular formof connection between the rib parts or sections, and which will prevent, to' a great extent, possibility of the cover being caught in the said connection. I Y

With these and other objects in mind, my invention resides in the details of construction, shown in the accompanying drawing, in which,

Figure-l, is an elevation of a stick and one rib and stretcher in the open position. Fig. 2, is a similar view of the stick and two ribs and stretchers in the folded position. Fig. 3, is a fragmentary plan view of the connection between the rib connections, showing the same provided with my improvements. Fig. 4, is a detail sect-ion, on an enlarged scale, through one of the supplemental connecting parts or members, and Fig. 5, is a detail cross-section, on an eularged sca-le, taken on line 5-5 of Fig. 3.

Referring now to these figures, my improved umbrella comprises a stick in three sections, an inner or handle section 1, which carries the handle la, an intermediate scction 2 which telescopes into the handle section, and an outer section 3 which telescopes into the intermediate section, the latter carrying the crown piece 3a to which the inner ends of the inner rib sections 8 are pivoted. The stick sections 1 and 2 carry inner and outer runner catches f1 and .5 respectively, which control the runner G, to which the inner ends of the stretchers 7 are a specification. invention relates to folding particularly to that charac- ,mediate side ears 11 and also operate to hold the stick section extended, it Ibeing necessary'to depress these catches before the 'stick sections 2 ahd 3 can be telescoped into section 1.

Each of the innerrib sections 8 comprlses a pair of parallel rods, the outer ends of which are pivotally secured to the outer end, and at the sides, of a connecting member 10, securely fastened upon the inner end of the outer rib section 9. Thus Ito fold the ribs the outer sections 9 wardly and back upon the inner sections .8 until they lie between the rods of said inner sections, as shown in Fig. 2. .The connecting members 10 are provided with.- interwhich, in the open position, bear outwardly against the rods of the inner sections 8, these ears at the inner edges of said connecting members. Said connecting members 10 are furthe'r provided with slotted inner ends forming side extensions, between, and through, which are pivoted one end of the supplemental connecting members 1'2, these latter members 12 being constructed of a single piece of material bent to form parallel side pieces between, and through, the opposite ends of which are pivoted the outer ends of the stretchers 7. These side pieces ofthe supplemental members 12 just mentioned are connected at their lower edges, and adjacent their inner ends to which the stretchers are pivoted, by integral webs 13, which not only serve to form a more rigid structure, out tf.,

engage thc stretchers 7 in the open position and prevent the outer end of said stretchers from extending through the rods of the inner rib sections Sand puncturing the cover (not shown.) The outer surface of each connecting member 10 is longitudinally and transversely slity to provide a pair of tongues 14, these tongues being located opposite the ears 11, and bent upwardly and curved outwardly so that when the umbrella is unfolded and opened, these tongues which are forced to pass between the rods of the rib section 8, will spring .outwardly1 and engage said rods as shown clearly in Fig. 5, and at thc same time will push the adjacent portions of the cover (not shown) away from the connecting member, and to a great extent prevent catching and tearing of the cloth.

From this it will be seen that l provide being'located eo i' sections, the inner sections of which are corn posed oi spaced parallel rods, connecting members secured upon the inner ends of the venter sections, and upon portions of whieh the outer ends of said inner rods are pivoted, said eonneeting members having outstanding side ears, and extensions at one end, supplemental Connecting members, formed oit a single piece of materiali, and comprising side pieces pivoted at one end between said extensions, the outer ends of the stretebers being pivoted between the opposite ends of y said side pieces, and said side pieces being `Connected at their lower ,streteliers inipinge in edges and adjacent their last named ends by integral Webs orniing guards against which the ends of the the open position.

2. in a oiding umbrella, the combination of a sectional stick, a runner mounted to en Lese inner ends pivoted to said runner, ribs having 'their inner ends pivoted to the outer portion oi the stick and comprising inner and outer sections, the inner sections of which are coinposed oj spaced parallel rods, connecting members secured upon the inner ends of the outer sections, and upon portions of which the outer ends of said inner section ribs are pvoted, supplemental connecting members pivoted at one end to the inner ends of the first named nieinbers, and to the opposite ends of which are pivoted the streteliers, said first named connecting l members being provided With intermediate outstanding side ears at their inner edges, and having their outer surfaces longitudi nally and transversely slit, to provide tongues bent upwardly and curved outfslide upon said stick, stretebers having their wardiy7 opposite the said ears, to engage the rods of the inner stick sections in the open position. Y in testimony whereof aflix my signature in presence oftwo Witnesses.
